- CRYO-SEM investigations;
- structural analysis of ceramic suspensions
The present paper is focused on the visual characterization of the structure of aqueous, electrostatically stabilized suspensions, containing silicon carbide and wax particles. The visualization of ceramic slurries is carried out by CRYO-SEM investigations, which is a standard technique in biology and food process engineering. To our knowledge, this technique was not used in ceramic suspension characterization before. By manipulating the interparticular forces through a variation of the pH, different states of dispersion and agglomeration, respectively, were prepared and analyzed. Furthermore, slurries with a bimodal particle size distribution containing spherical 115 µm wax particles were examined. Such suspensions are used in the production of porous ceramic components.
